Gool), a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented acertain new and useful Belt-Fastener, of which the following is a specification.

This invention relates to belt fasteners, and it has for its object to provide a separable fastener of simple but strong design which will securely connect ythe belt ends and may readily be coupled and uncoupled.

My invention may advantageously be used on belts for careaXle lighting systems, oilwell pumps, and in otherv situations where the belt requires rather frequent removal or renewal.

Of the accompanying drawings,

Figure 1 is a plan view showing my improved fastener applied to a belt. l1.Fig 2 is a section on the line 2-2 of Fig. 3 is a section on the line 3f-3 of Fig. 1.

In the drawings, 10, 11 are the two ends of an ordinary flat power belt. 12 is a keeper-plate forming one main member of the coupling or fastener and secured on the upper side of the belt-end 10 by means of pronged rivets 13. Ears Mare turned up on the two ends or side edges of this plate, and said ears are formed with slots or apertures 15, 15a for the reception of the keyplate or retainer.

16 is a hook-plate constituting the other main member of the coupling, this plate being provided with an attaching portion 17 secured to the beltend 11' by means of pronged rivets 18, and an upwardly-offset arched portion 19 which overlies the keeperplate 12 between the ears 14 thereof and has a down-turned ange 2O hooking over the rear or remote edge of said keeper-plate. This overlying portion 19 is lightened with holes 21. Both plates are slightly curved longitudinally to approximate the curve of the belt when rounding the pulleys.

22 is a fiat key or retaining bar overlying the hook-plate 17 and passed through the slots 15, 15a in the ears of the keeper-plate. The hook-plate 16 is grooved or depressed at 26 to receive said bar. The bar is longitudinally divided for about half its length to form a' pair of spring arms 23, and said arms are notched or recessed at 24; on their vSpec ification of Letters Batent; Application filed June 20,1918.

, outer edges," near one end, to receive'a pair 'of liofizionta'lt'lips 25 formed-on th'evplate 16, Athe*"extremities 2,3@l and the shoulders 23b of the spring arms hooking around the edges of these lips so as to lock the bar 'against displacement when the arms are in their normal positions. The particular form of and manner of mounting the retainer, as well as other features of construction, may be considerably varied without departing from my invention.

When the parts are assembled in their olperative relation as shown in the drawings, t e ends of the belt are securely coupled together, and the longitudinal separating strain is taken by the engagement of Hange 20 on the hook-plate with the rear edge of the keeper-plate 12. As there is substantially no wear at this interlocked joint, there will be little or no tendency of the ends of the belt to draw apart when in use. As both members of th'e fastener are located on top of the belt, there will be no metal parts in contact with the pulleys if the prongs of the rivets 13 and 18 are clenched substantially Hush with the belt surface as shown. To uncouple the fastener, the spring arms 23 are pressed together by hand or with any suitable tool to unlock them from the lips 25, and the retaining bar 22 is slid through the ears 14 from its operative position. The hook-plate 17 may then be disconnected from the keeper-plate l2 by a relative sepa rating movement of the belt ends transverse (to the plane of the belt. To re-couple the fastener, the foregoing operations are reversed as will be evident. f

I claim:

1. In a belt fastener, the combination, with the belt, of a keeperplate on one end, a hook-plate on the other end interlocked with said keeper-plate, and a withdrawable retainer interlocked with one of the plates, for maintaining said plates in interlocked relation.

2. In a belt fastener, the combination, with the belt, of a keeper-plate on one end, having upturned ears, a hook-plate on the other end interlocked with said lkeeper-plate and overlying the same between the apertures in said ears, and means o n saidv hook-plate interlocking with said bar for retainingthe latter in position.

4." ln ar belt fastenerg the combination -of a keeper plate adapted for attachment to 1o one end of the belt, a hook-plate adapted for attachment to the other end and interloeked with said keeper plate, and a sliding retainer bar for Yholding` Said plates in -interlocked relation, said bar being formed With a pair yof spring arms adapted to interlock the bar vvitlfone of said plates by their separating v movement.

In testimony whereof I have hereunto set my hand this: 18 day of June, 1918.
